Whyalla ranks 303rd in South Australia out of 347 postcodes in the Clean Energy Regulator dataset, with 46 registered systems to date. Growth has been strong, with 7 new systems installed in the past 12 months — a 600% increase on the previous year, making Whyalla one of South Australia's faster-growing solar postcodes.
Whyalla's solar systems avoid an estimated 208 tonnes of CO₂ per year, equivalent to 99 fewer cars on the road annually. This is estimated using South Australia's average grid emissions intensity of 370 gCO₂/kWh, sourced from OpenElectricity, applied to an average system size of 9kW.
